TORONTO, June 4 (Reuters) - Canada's main stock index fell
on Thursday as a tumble in oil prices stung energy producers and
bucking bond markets had investors backing away from utilities
and pipelines.

Investors are jittery about a slew of unresolved issues in
global financial markets, including uncertainty around when the
U.S. economy will be judged strong enough to merit Federal
Reserve rate hikes.

"The bond markets are forcing investors' hands, they are
making a move ahead of any central bank rate hikes that may or
may not come over the next year or two," said Elvis Picardo, a
strategist at Global Securities in Vancouver.

"With higher yields you're paying more for debt," he said.
That hurts debt-reliant sectors such as utilities, which fell 2
percent, and pipelines such as Enbridge Inc, the
heaviest individual weight on the index with a 1.9 percent
retreat to C$59.19.

The Toronto Stock Exchange's S&P/TSX composite index
ended down 135.29 points, or 0.89 percent, at
15,019.39. All 10 main sectors on the index fell.
